Air in a piston-cylinder assembly is compressed from an initial state where T1 = 300 K and 1.0 bar to a final pressure of 10 bar. Assume that air behaves as an ideal gas and the process is adiabatic and internally reversible process: (a) Write down the first low and the second laws of thermodynamics for a closed system and simplify them for this problem. (b) Determine T2, in K, assuming variable specific heats (c) The work, in kJ/kg, assuming variable specific heats (d) Recalculate part (b) and (c) assuming constant specific heats.
